need help choosing rcr123a for quark 123x2

I have the 4sevens Single-Bay Smart Charger. Im looking into getting 2 rcr123a batts. But dont know what ones to get. These are the ones Ive looked at so far:

TrustFire 880(goinggear) - looks to be too long?
UltraFire (BatteryJunction) - looks just like the TrustFire, might be too long?
Tenergy 30201 RCR123A 3.0V (BatteryJunction) - dont know anything about these
Tenergy 30200 LiFePO4 (BatteryJunction) - dont know anything about these
AW Protected (cpf) - looks good

What should this noob get for his Quark 123x2

It looks like you already know.

Yeah, just needed to be sure. Thanks for the link too. Didnt know about his site. Makes it easier for me to order

Get the AW 17670 for the quark 123x2.

Whys that?

the solarforce 16340's fits perfectly in my quarks, but their capacity is way below the rated 880mAh.

The Quark X will have a slightly higher output when using 2 RCR batteries.
See the Ti-force review:

1x17670 should have have a longer life than 2x16340. Though Lou did point out that the higher electrical potential energy of 2x16340 will provide a brighter output.

Also I thought Quarks accepted 18650...? I've never tried it before...

Electrically speaking, Quarks can accept an 18650 - however physically the 123^2 bodies won't. At one time 4sevens offered an 18650 body only for quarks (which I own and would never part with, they're awesome), but I believe they have been discontinued for some time now. - Maybe check the WTS, WTT, WTB forums for a used one?
